Reconciliation is not a Sacrament to Lutherans, so no Grace is bestowed by a Lutheran Pastor when he declares absolution; he is merely interpreting the reduced Lutheran bible by his own understanding of the Word, for he believes in the Word Alone, his own understanding that Jesus spoke to him, the Pastor, via the pages of the book, that he could tell people they are forgiven, even though Jesus was talking to 11 other people when he literally and materially breathed on them in person and said to the 11, “Receive the Holy Spirit; if you forgive the sins of any they are forgiven; if you retain the sins of any they are retained.”
So, the Lutheran Pastor (all of them, actually) is presuming to be one of the eleven disciples spoken of in John’s Gospel, even though they would not be born for 2000 years. With no Apostolic dispensation of the same gift and the Apostolic interpretation of the same, Lutherans are pretending, thinking that some kind of “kerygma” is empowering their speech, for they deny it as a Sacrament, and deny Grace is anything but a “favoring by God”, when in fact it is substantially the presence of the Holy Spirit infusing virtue into the Penitent.
Lutheran Absolution came about with the continued practices of the Catholic Church as pious behavior while eliminating any supernatural expectation of the pious behavior, as in Sacraments. Even in Lutheran Sacraments (Communion and Baptism) there is no actual and indelible change to the person - infused Grace and Virtue.
I say this as a former Lutheran Pastor.
